The web interface
Lock aperture
adjust the aperture size. You can, for example, lock the aperture for scenes with permanent light conditions.
Aperture
: Use the slider to adjust the aperture size, that is, how much light passes through the lens. To allow more light
to enter the sensor and thereby produce a brighter image in low-light conditions, move the slider towards Open. An open aperture
also reduces the depth of field, which means that objects close to or far from the camera can appear unfocused. To allow more of
the image to be in focus, move the slider towards Closed.
Exposure level: Use the slider to adjust the image exposure.
Defog
: Turn on to detect the effects of foggy weather and automatically remove them for a clearer image.
Note
We recommend you not to turn on Defog in scenes with low contrast, large light level variations, or when the autofocus is
slightly off. This can affect the image quality, for example, by increasing the contrast. Furthermore, too much light can
negatively impact the image quality when defog is active.
General
Name: Enter a name for the selected camera.
Stream
General
Resolution: Select the image resolution suitable for the surveillance scene. A higher resolution increases bandwidth and storage.
Frame rate: To avoid bandwidth problems on the network or reduce storage size, you can limit the frame rate to a fixed amount.
If you leave the frame rate at zero, the frame rate is kept at the highest possible rate under the current conditions. A higher
frame rate requires more bandwidth and storage capacity.
Compression: Use the slider to adjust the image compression. High compression results in a lower bitrate and lower image quality.
Low compression improves the image quality, but uses more bandwidth and storage when you record.
Signed video
adding cryptographic signatures to the video.
Zipstream
Zipstream is a bitrate reduction technology, optimized for video surveillance, that reduces the average bitrate in an H.264 or H.265
stream in real time. Axis Zipstream applies a high bitrate in scenes where there are multiple regions of interest, for example, in scenes
with moving objects. When the scene is more static, Zipstream applies a lower bitrate, and thereby reduces the required storage.
